The photo on the top right is from Kirbie's Cravings. The bacon's not really a bowl in this case, but rather a ring holding an egg. I made these this morning using Kirbie's recipe, and they were the cutest and tastiest breakfast cups. Essentially, you start with either pre-cooked or halfway-cooked bacon molded into a circle in the muffin pan and crack the egg into it. Check the site for the recipe and other variations, including adding avocado or putting a circle of toast at the bottom of the regular-size muffin pan.

Megan at Not Martha showcases yet another bacon cup, this time made by weaving the bacon strips onto the back of a muffin pan (i.e., turn the muffin pan over, like you do to make cookie bowls or taco bowls). Fill with lettuce and tomato, and you've got a breadless BLT.
